  • a tire pressure sensor is installed on a gas nozzle of a hub of each tire.
  • the system also includes a sensor enclosure, a stem, kinds of sealing members and fasteners. Components for example a tire pressure-sensing element and battery are contained in the sensor enclosure. No matter whether the car is moving, the tire pressure sensors real time automatically monitor pressure and temperature of the tires, and provide alarm when the tire pressure and temperature is abnormal, thus avoiding traffic accidents due to malfunction of the tires and keeping safe operation of the car.
  • a prior art tire pressure sensor fails to adjust the angle between itself and stem. This limits application range of the sensor, and the sensor is restricted to be mounted in a specific wheel hub.

  • a gap is defined between the plastic injection hole 19 and top surface of the circuit board 120; another gap is defined between the plastic injection hole 19 and bottom surface of the circuit board 120; and therefore, liquid material may be injected into the top and bottom surface of the circuit board 120 via these gaps, thus eliminating problem of incomplete getting rid of air from the enclosure due to injection of liquid material from only one side of the circuit board 120, and reducing time for getting rid of air, and improving efficiency.
  • the plastic injection hole 19 is close to the metal pad 53.
  • the plastic injection hole 19 is defined in the side plate 103 which is away from the first threaded embossment 512, thus avoiding changing location of the enclosure when securing the circuit board 120 with the enclosure 10 using the screw 3 and injecting liquid material into the enclosure 10 through the plastic injection hole 19, facilitating the entire production line, and improving production efficiency.
  • the metal connection member 5 is constructed of the metal pad 53, bending arm 52, supporting tab 54, and second axle bed 51 integrally, and it realizes functions of antenna passage, fixation of the gas nozzle, and gas incoming path communicated with the intake hole. Consequently, the tire pressure gauge 100 has compact and efficient structure, and entire size of the gauge is reduced. Moreover, the metal connection member 5 is mounted to the enclosure 10. In other words, when placing the metal connection member 5 into a mold for realizing connection of the member 5 and enclosure 10, the vent hole 542 of the supporting tab 54 of the member 5 will align the member 5 with the mold, thus accelerating molding of the enclosure 10.
